Preparation of Ozone Catalysts by Copper Manganese and Iron Oxide and their Effects in Organic Removal

Abstract:

In this study, three kinds of catalysts for ozone catalytic were fabricated and their effects on organic removal were investigated, moreover the influencing factors in manufacturing were investigated by orthogonal experiments. The prepared Cu/Al₂O₃, Mn/Al₂O₃ and Fe/ Al₂O₃ improved UV₂₅₄ removal of ozone by 12%, 3% and-2%, when ozone was combined with activated carbon filtration, the removal of UV₂₅₄ was improved by 16%, 14% and 8% respectively. Cu/Al₂O₃ was chosen as a model catalyst and its effluencing factors in preparation, including impregnation concentration, impregnation time and calcinations temperature, were analyzed in orthogonal experiments. The orthogonal experiments showed that impregnation time has the biggest effluence in catalytic effect, which followed by calcinations temperature and impregnation concentration.
